# TSI vs Impluse

The clearest difference is device support: TSI at 3 against Impluse's 1. TSI also leads on iOS requirement (14.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. TSI sells 8 in-app purchases, starting at $7.99 per month and Impluse sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
